We present a new 2-ary elliptic curve point multiplication method with resistance against side-channel attacks. This method provides two advantages compared with previous similar side-channel attack countermeasures: It avoids a fixed table, thus reducing potential information leakage available to adversaries; and it is easily parallelizable on two-processor systems, where it provides much impro...

We study the role of coded side information in single-server Private Information Retrieval (PIR). An instance PIR problem includes a server that stores database K independently and uniformly distributed messages, user who wants to retrieve one these messages from server. consider settings which initially has access linear combination subset M database. assume identities form support set as well...

This paper presents a conceptual model to explain employee security behaviors as a function of manager’s transgressions in the workplace. To date, most information systems security (ISS) studies neglect the effects poor leadership can have on the security of organizational ISS. This paper seeks to broaden the study of leadership in information systems security by examining negative effects of l...

The second generation of digital video broadcasting (DVB-T2) standard utilizes orthogonal frequency division multiplexing (OFDM) system to reduce and to compensate the channel effects by utilizing its estimation. Since wireless channels are inherently sparse, it is possible to utilize sparse representation (SR) methods to estimate the channel. In addition to sparsity feature of the channel, the...
